logregWBY: Bianco and Yohai estimator for logistic regression
Description
This function computes the weighted M-estimator of Bianco and Yohai in logistic regression.
By default, an intercept term is included and p parameters are estimated. Modified by
Yohai (2018) to take as initial estimator a weighted ML estimator computed with weights
derived from the MCD estimator of the continuous explanatory variables. The same weights
are used to compute the final weighted M-estimator. For more details we refer to
Croux, C., and Haesbroeck, G. (2002), "Implementing the Bianco and Yohai estimator for
Logistic Regression"
